My friend has a projector. The size of the screen he has at the moment is 3m wide by about 2m high. He has the projector in 16:9 widescreen mode. If he played a dvd on it, that was linked to the projector with OFC Scart cables or the best you can get, with a bitrate of 5000kb/sec for video on the dvd. Will the picture look fine? Or will it look pixel like?
If so what bitrate do i need to get a decent picture.

A fast responce would be appreciated.

Hi, I dont know if it helps but someone I knew connected a old but really good Barco projector to his DVD player via the video phono plug from the Scart out plug, and connected the AV left and right plugs to a hifi. The result was an excellent picture and the screen was about 7m by 4m wide. I dont know if that specifically helps your question, but thats how I know that when used correctly DVD players and projectors work really well.

I thought the bitrate was set by the disk, not the user

If the projector is good quality you should get a very good picture

You're dealing with a fixed resolution on DVD (which will be downsampled to lower res for a 16:9 DVD with player set to 4:3 letterbox), and a fixed resolution for a projector (again, some up/down sampling may occur if the DVD and projector aren't the same resolution). Many, but not all, projectors have a 16:9 panel (best for home cinema) rather than a 4:3 panel (best for PCs). Play DVDs on a 4:3 projector and only about the middle two thirds of the panel is actually used (same as 4:3 letterbox). The lower the resolution vs the bigger the screen, the more noticeable the pixellated structure of the image (even more noticeable with LCD and the "chickenwire" effect, DLP kind of solves this). You could even probably with a bit of math figure out the size of a pixel when blown up on your huge screen. By playing about and slightly defocussing the image you could probably reduce the pixellated appearance.

Other factors: picture/encoding quality/bitrate - the picture is only as good as the source, and a big screen will really highlight crappy pictures, also get rid of interlacing (noticeable on large screens, progressive-scan component signal or some kind of de-interlacing required), avoid cheap DLP projectors which give the dreaded "rainbow" effect, kill ambient light for best black level/brightness/contrast. But projectors (even 1500-quid LCD ones) can look really good these days.
